Slags from the Iron and Steel Industry. Background With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a

Carlos Thomas, Francisco Agrela, in New Trends in Ecoefficient and Recycled Concrete, 2019. Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.

LD Slag in construction of Hardstands. A hardstand is a paved area for parking heavy vehicles, storing raw materials/ finished products etc. Due to better strength, abrasion and impact resistance than natural aggregates, Steel Slag aggregates are particularly suitable for use in areas subjected to heavy vehicle loads and high shear stress.

SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and nonferrous (copper, lead/zinc) depending on the industry from which

Steelmaking slag is generated by the process that turns pig iron produced by a blast furnace into tough and highly workable steel. Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components from the pig iron and refine it to produce strong
